The basal geomorphology structure of the Tidal-Basin System of the Tiaozini Sandbanks is watershed and tidal creek system. We analyses its formation, evolvement, geomorphology characters and development and discusses the main influence factors which is water, sediment and space. We divide the evolution phases which is formation phase, autumn phase and contabescence phase. In the end we confirms its main functions, which is discharging the folium water on the tidal flat of the Tidal-Basin in the end of the ebb-tide, transporting sediment to Tidal-Basin through tidal creek systems, confining the swing range of the dynamical axis of flood tide or ebb tide, balancing the dynamical status of the South and North. At the same time, we compare coastal tidal-basin and sandbanks tidal-basin on geomorphology characters, formation causes, style and so on.

Is the short crack structure may explain certain landform growth origin question in the short crack structure aspect's significance; The short crack structure causes the epeirogenesis causes the earth's crust material to be destructed this to contain the ore solution to provide the good migration channel and stores the place and so on five aspects.

在短裂构造方面的意义是短裂构造可以解释某些地貌发育的成因问题；短裂构造引起的地壳变形，使地壳物质遭到破坏，这就为含矿溶液提供了良好的迁移通道和贮存场所等五个方面。

Based on technical processing of high-resolution SPOT images and aerophotos, detailed mapping of offset landforms in combination with field examination and displacement measurement, and dating of offset geomorphic surfaces by using carbon fourteen (14C), cosmogenic nuclides (10Be 26Al) and thermoluminescence methods, the Holocene sinistral slip rates on different segments of the Altyn Tagh Fault are obtained. The slip rates reach 17.5 mm/a on the central and western segments west of Aksay Town, 11 mm/a on the Subei—Shibaocheng segment, 4.8 mm/a on the Sulehe segment and only 2.2 mm/a on the Kuantanshan segment, a easternmost segment of the ATF. The sudden change points for loss of sinistral slip rates are located at the Subei, Shibaocheng and Sulehe triple junctions where NW-trending active thrust faults splay from the ATF and propagate southeastward.

在高分辨率SPOT卫星数字影像和大比例尺航片处理、断错地貌制图、野外核实与位移测量基础上，利用宇宙成因核素（10Be、26Al）、碳十四（14C）和热释光等多种测年手段，厘定了各断错地貌面的形成年龄，得到了阿尔金断裂带不同段落全新世左旋走滑速率：阿克赛以西的中、西段左旋走滑速率可达17.5 mm/a，肃北—石包城段为11 mm/a左右，疏勒河口段减少到4.8mm/a左右，东端宽滩山段仅约2.2 mm/a，左旋走滑速率突变点位于阿尔金断裂带中东段存在分支活动逆断层向南东扩展的肃北、石包城和疏勒河等三联点上。

Corrosion process of water flow could have great impact on dissolvable rock area in several decades.

岩石风化作用既是地壳固体物质形态转变的重要途径，也是产生块体运动灾害的必要前提条件，其类型和强度受区域气温及降雨条件的控制；水的侵蚀作用的区域性规律受地貌成因和气候条件的制约，它对陆地环境的最大冲击是对海洋、湖泊及水库岸滩带的侵蚀和改造；流水的溶蚀作用可在几十年内对可溶岩类地区产生影响。

In order to explore the grain-size distribution characteristics and geo-genetic types of land desertification in Mo Us desert, the research on the grain-size characteristics of sediments since late Pleistocene has been carried out in the desert area and neighboring area such as inside desert, sand covered loess plateau, loess plateau and river valley. The research result shows that sediments of different geologic genetic types are the fundamental material source of sandy desertification in these areas and the distinguishing of different types of the sediments is the theoretical basis of classification of different geogenetic type of sandy desertification. The contribution of different geological roles on the land desertification and its significance to prevent and deal with the land desertification have also discussed.

为了研究毛乌素沙地沉积物的粒度特征与土地沙漠化的地质成因类型，通过系统研究沙地及相邻地区晚更新世以来在沙地内部、覆沙黄土区、黄土高原和河流谷地与湖泊等不同地质构造地貌条件下所形成的沉积物粒度特征，指出不同地质成因类型的沉积物是这些地区土地沙漠化的物质基础，区分不同类型的沉积物也是构成不同地质成因类型土地沙漠化分类的理论基础，探讨了不同地质作用对土地沙漠化的贡献及其对土地沙漠化防治方面的意义。

Although different geomorhopologic landscapes appeared unique geological characteristics because of the difference of their formation, the formation of geornorhopologic landscapes are related to the Geologic-tectonic evolutional history and the multicycle magmatic activities, especially the neotectonic movements.

尽管不同类型的地质地貌景观由于成因上的差异而显现出独特的地学特征，但地质地貌景观的形成均与新疆复杂的地质构造演化史和多旋回的岩浆活动、尤其是新构造运动密切相关。

The study results show that:①The distribution of Cd in shallow surface soils is characterized as: The content of Cd in lacustrine deposit, alluvial lacustrine and alluvial-diluvial low-lying plain is 1.4 to 1.8 times as high as in alluvial-diluvial high valley flat and alluvial-diluvial high bank physiognomy areas.②The content variation of Cd in horizontal distribution was controlled by clay primarily and OrgC secondly. The variation of OrgC was major factor that affected the content variation of Cd in vertical distribution.
